Audrey Hepburn announced the assassination of Pres. John F. Kennedy to the devastated cast and crew immediately after filming the number "Wouldn't It Be Loverly?" on the Covent Garden set on 22 November 1963.

Late in the movie, when Scott is mostly "de-Santafied", he captures the Tooth Fairy. The Tooth Fairy, doubting that Scott is Santa Claus, tells him "I know Santa Claus. I'm friends with Santa Claus. You're no Santa Claus." This is a parody of [?] Lloyd Bentsen's famous retort to [?] Dan Quayle during the 1988 US Vice Presidential debate, comparing him with 'Jack Kennedy' referring to John F. Kennedy.

When then President John F. Kennedy listed Ian Fleming's book among his top ten favorite novels of all time, a list published in [Life Magazine], March 17, 1961, the producers decided to make this the second [James Bond] movie. According to the book Death of a President (1964) by [?] William Raymond Manchester, this was the last motion picture JFK ever saw, on a private screening in the White House, November 20, 1963.
